AI Model

Claude 3 Sonnet is the mid-tier model in the Claude 3 family, released by Anthropic in March 2024. It balances speed, cost-efficiency, and strong performance on tasks like coding, reasoning, and multimodal understanding. The model is optimized for scalable deployments and agentic workflows. Claude 3 Sonnet was trained on the same proprietary mix of data as Claude 3 Opus (public internet data up to August 2023, private datasets, and internally generated data). It underwent RLHF and Constitutional AI fine-tuning to align with helpfulness, honesty, and harmlessness. The model is multimodal (text and vision) and multilingual. Safety evaluations show strong alignment, with low rates of harmful outputs and high resistance to jailbreaks. It was deployed under AI Safety Level 2 (ASL-2) protections.
